Why are Coqui a problem?

Males produce a continuous two-tone "ko-KEE" mating call at night that can be as loud as a chainsaw.

Coqui identification

One of many color phases of coqui frogs

Female, and male brooding eggs Coqui vary greatly in color from brown, tan, to yellow (and even red or black), with or without a stripe down the back, and occasionally with stripes on the sides of body or head.

Females are much larger than males. Males call loudly; females have a softer rasping call to defend territory.  Calls usually start with a “warm up” repetition of the first note, “ko,” a territorial call to other males, and then the characteristic “kee” call to attract females.  Visit the HEAR website to hear the range of calls coqui make. Coqui are reported to live 4-6 years and continue to increase in size as they age.  It is not surprising then that island coqui seem to be getting bigger, now that they have been on the island for over 10 years.  Coqui are similar in appearance to the greenhouse frogs, only much larger. The call of the greenhouse frog is much quieter and has been characterized as a “cricket-like chirping.”  Check the CTAHR website for a detailed comparison between the two closely related frogs, both accidentally introduced to Hawaiʻi.
